.vented certain improvements in Antifriction-Bearings, of which thefollowing is a specification.

' My invention is an improved antifriction bearing comprising asectional journal loox having means for holding its parts together,l

in combination with balls and rollers related so that one setof devicesact as spacers for the other, and means whereby the balls and rollersare held in the separated bei: sections.

The characteristic features of my ini:- provenents are more fullydisclosed in the following description and the accompanying drawings inillustration thereof.

ln the dranf'ings, lligure l is a longitudinal sectional view of a formof my improved bearing applied to a shaft; Fig. E2 is a transversesectional view of the construction illustrated in Fig. l; l? ig. 3 is alongitudinal sectional view of a second form of bearing embodying myinvention; Fig. 4 is an end view of the bearing illustrated in Fig. 3;lfig. 5 is a broken longitudinal section of a third form of hearingembodying my improvements; and Fig. G is a broken longitudinal sectionof a fourth form of bearing embodying the invent-ion.

rlhe bearing, as illustrated in `Figs. l and 2, comprises a box composedof the sections l and 2 having the interlocking longitiulinal flanges orribs l and 2 for holding them against lateral movement, the sectionsbeing fixed together in theirl operative position by screws 3 settherein. Sectional rings et tit within the ends of the semi-cylindricalbearing surfaces of the respective box sections Where they are held hyscrews 5 Whichpass through slots (3 in the box sections, whereby thering sections are adapted to he moved parallel to their axis. The ringsare provided with sockets 4 adapted for engaging the ends of rollers 7and holding them within the looX sections, upon the inner cylindricalsurface of which they are designed to roll. rlhe box sections .areprovided with circular races S andthe rollers are provided with thecircular races 9, in which races balls l() are engaged. 'lhcse ballsspace the rollers, are held in position thereby, and hold the rollersagainst endvvise movement. rllhe separated Specification of LettersPatent.

box sections l and 2, with the balls l() and rollers 7 held therein bythe engagement of the ring sections d with the latter, can be coupledupon the shaft. ll by engaging the flanges l and 2 and inserting thescrews 3. rlhe bearing being thus conveniently placed upon anyintermediate section of the shaft, the rings are shifted out ofengagen'ient with the rollers, by loosening the screws 5, and held outof' engagement by sett-ing the screws.

its illustrated in Figs. .3 and 4l, the shaft l2 has applied thereto abearing collar or sleeve comprising the cylindrical sections 13 havingon the ends thereof the circular' chanr nels 13, the sections beingclamped on the shaft hy springing the open rings or ring sections leinto tne channels. he hox'sections l5, with. the corresponding rollers17 and balls engaged within there by the ring sections i9 and screws 20,are then placed on toe colla-r and fined together oy screws 2l whichpass through lugs 22 on tire box sections. The parts being thusassembled, the screws 20 are loosened and the rings 19 are moved out* ofengagement with the rollers i?, Where they are held by resetting thescrews, slots 23 being provi-ded in the looX to permit the movement thescrews longitudinally of the rollers. rEhe halls are engaged in theconcentric races 24 and 25 of the collar and non and engage the races Q6of the rollers, whereby the balls and rollers are held in the desiredrelation.

In Fig. 5, there is illustrated a vrfiodifled. form of ring comprisingthe pressed metal sections Q7 having sockets in the forni of notches 2?therein for engaging the ends of the roller-S28, which are spaced by andhold the halls conveniently hy pressing sheet metal into the form of acircular channel. rlhese channels are engaged in adjustable relation tothe box sections by the screws 3l which pass through the slots 32 in theboxes.

Fig. ti illustrates a further forni of ring comprising complementarypressed metal parts33 of Z-shaped cross section, having legs 33 bearingon the cylindrical interior surface of the box sections Se' and the legs33 provided with the sockets or notches 33l adapted for engaging theends of the rollers 35 which bear upon such surface, the legs 33', beingengaged ley screws 36 which pass through the slots 37 in the loonwhereby the rings can he shifted into or out of engagement with tlierollers.

29, the rings being produced Gil' It Will be understood that to avoidgrinding action between the balls and rollers, Whether the balls or therollers be used as spacers, such spacers Will be relieved of the load,by reducing their diameters sutliciently, While the other Will carry theload.

Having described my invention, I claim:

l. An antifriction bearing comprising a journal box having a race,rollers having races registering With said races first named, ballsdisposed between said rollers in said races,

rings adjustable in said box, said rings having sockets adapted forengaging the ends of said rollers to lock them to said box, and screwsadjustable in said box whereby said "rings are heldin several positions.

2. An antifriction bearing comprising a journal box containing a race,alternating balls and rollers containing races, said balls acting in theraces of said box and rollers, an adjustablering having a leg adapted toengage said box and a` leg adapted to engage said rollers, and meansfonholding said ring in said box in and/out of engagement with saidrollers.

3f An antifriction bearing comprising a sectionalfjou'rnal box, means,for fixing said sections-together, a sectional ring of pressed metalhaving a leg adapted to engage said box andA a notched leg adapted toengage the ends of said rollers, and means for connecting said ring tosaid box in and out of engagement with said rollers.

4. An antifriction bearing comprising a sectional journal box, rollersdisposed in said box, sectional rings, and means Whereby sections ofsaid rings are engaged to and movable relatively to correspondingsections of said box, said sections being adapted for engaging saidrollers to and permitting their disengagement from sections of said box.

5. An antifrictionbearing comprising a sectional journal box having arace therein, means Ifor holding said sections together, a

sectional collar, open rings adapted to be spr-ung on the ends of saidcollar to hold the sections thereof together, alternating balls androllers between said collar and box, said balls being engaged in saidrace and holding said rollers against endwise movement, and adjustablerings Which in one position thereof lock said rollers and in anotherposition thereof permit movement of said rollers.

6. An antifriction bearing comprising a box, a collar, one of said partshaving a circular race therein, alternating balls and rollers disposedbetween said box and collar, said rollers having circular races thereinand said balls being engaged in said races, and adjustable rings`movable into and out of engagement with the ends of said rollers.

7. An antifriction bearing comprising a .sectional box having a circularrace therein, alternating balls and rollers in said box said rollershaving circular races therein and said Vballs being engaged in sai-draces, and rings adjustable in said box into and out of engagement withsaid rollers. l

In Witness whereof I have hereunto set my name this 19th day ofJanuary,l91l, in the presence of the subscribing Witnesses.
